PAPER-FASTENER.

SPECIFICATION forming part of Letters l atent No. 593,683, dated November 16, 1897 Application filed May 25, 1896. Serial No. 592,932. (No model.)

teners, of which the following, taken in connection with the accompanying drawings, is a specification suffi'ciently full, clear, and accurate as will enable those skilled in the art to which it appertains to make and use the same.

The object of my invention is the production of a paper-fastener for holding together at the corners or margins assembled sheets of paper, and which shall be cheap in cost, simple in construction, and easily and quickly applied.

' With these objects in view my invention consists in cutting thin sheet metal to proper form and dimensions, fashioning a tongue, and making an opening to receive the corners or margins of sheets of paper.

It still further consists in certain novelties of construction and combination of parts hereinafter described, and specified in the claims;

Similar parts are designated by the same numerals of reference on the accompanying drawings.

Figure 1 is a view of the preferred form of Fig. 2 shows the same form with sheets of paper inserted in the opening and the tongue turned down thereon. Fig. 3 illustrates the same fastener with the upper jaw bent down and firmly securing the paper in position. Fig. 4 is an obverse View of Fig 3. Figs. 5, 6, and 7 show modified forms of of metal.

Fig. 1, the dotted lines in each indicating-the corners of sheets of paper inserted in the openings preparatory to turning down the tongue and bending. Fig. 8 is a View of a form of fastener. especially adapted for fastening assembled sheets of paper at the margins. Fig. 9 is a view of the fastener shown in Fig. 8 with the upper jaw and tongue folded over and gripping the margins of the sheets of paper. Fig. 10 is an obverse View of Fig. 9. a form like Fig. 5, but with an added section Figs. 15,16, 17, and 18 illustrate additional modifications of my fastener.

I make each of the several varieties of the fastener out of thin sheet metal and of any Figs. 11, 12, 13, and l lillustrate suitable shape and configuration. An opening for the reception of the corners or margins of sheets of paper is formed by cutting the body of the metal, and a tongue likewise fashioned and adapted to be turned down and grip the paper preparatory tothe act of bending. To insure the bending of the metal on the proper line, I make a score orseveral fine scores adjacent one to another across the metal. The tongue I also make ofsuch a length that when it is turned down its outer edge will lie adjacent to and parallel with the score or scores. When thin sheets of paper are to be fastened together, a single score is sufficient, but where the paper is thick several parallel scores are preferable to provide ample space between the upper and lower jaws and at the scores for the folds in the sheets. To secure stiffness and rigidity, and to facilitate the bending of the jaw on the line of the score and not through the corrugations,'I preferably corrugate the metal vertically throughout except on the line of the score or scores. In place of the corrugations, however, I may use other means for securing vertical stifiness and rigidity, such as result from striking up portions of the metal in a die or embossing it in any suitable way.

The fastener as thus described may in each of its varieties, when desirable, be made with an additional section for the purpose of providing for a second bending of the metal upon itself, so as to secure a firmer gripon the paper.

The several parts of the fastener are designated by numerals in the Views, as follows:

1 is the upper jaw; 2, the lower jaw; 3, the tongue; 4, the score; 5, the corrugations; 6, the opening to receive the corners or margins of the assembled sheets of paper; 7, corners or margins of sheets of paper, and 8 an ad- Figs. 5, 6, and 7 are slightly-modified forms of the fastener shown in Fig. 1, Fig. 5 having an opening 6 of less area, Fig. 6 having the corners cut 0E and an opening like Fig. 5, and Fig. 7 being made round or oval and without sharp corners.

The modification in Figs. 8, 9, and 10 is especially adapted for application to the margins of assembled sheets of paper, and to that end is fashioned with a long upper jaw l and tongue 3. The sheets of paper 7 are inserted under the tongue 3, as shown, the tongue then turned. down, and finally both tongue and up per jaw bent over to the position shown in Fig. 9. The position of the lower jaw 2 appears in Fig. 10.

The forms shown in Figs. ll, 12, 13, and 14 are like that in Fig. 5, with an additional section 8 attached. The insertion of the paper and bending is similar to the practice in the forms described except that the metal is subjected to a further bending on the line of the lower score 4:.

Fig. 13 shows the relative position of the parts at the end of the first or preliminary bending, and Fig. 14 the position taken as the result of the second bending.

In Figs. 15, 16, 17, and 18 I introduce several slight modifications in construction, the tongue occupying in each case a position at the upper edge of the upper jaw 1 and the opening for the paper being in the tongue and not in the jaw proper. The insertion of the paper and turning down of the tongue and bending of the upper upon the lower jaw is analogous to the operation previously described in connection with the other forms. In these figures, 1 is the upper jaw; 2, the lower jaw; 3, the tongue; 4, the score; 5, the corrugations; 6, the opening, and 7 the sheets of paper.

It will be observed that in all the forms illustrated the tongue when turned down occupies a position with its edge adjacent to the score or scores and that when the upper jaw is bent the edge of the tongue forces the folds in the paper against the score or scores and that the jaws grip it and hold it securely and firmly.

In practice I may make the fasteners, as shown in the drawings, with the tongue projecting at an angle to the plane of the body of the metal, or the said tongue may lie in the same plane as the body of the metal and be turned up by hand preparatory to the insertion of the sheets of paper and the fastening of them.

From the foregoing it will be seen that I have produced a fastener of simple construction, made of very light metal, cheap in cost, and adapted to be applied with fewer manipulations than any other of a similar style and character heretofore known.

Finally and particularly, while I have illustrated and described by way of example several specific physical embodiments of my invention, I do not in omitting the description and illustration of other embodiments intend to limit myself only to those set forth, inasmuch as other shapes may be devised which will obviously be within the scope and terms of my invention and claims.

What I claim as new, and desire to secure by Letters Patent, is-

1. A paper-fastener consisting of a thin plate of metal out to shape, said plate being provided with an opening in the body thereof for the reception of assembled sheets of paper; an upper jaw; a lower jaw; and a score struck up from the metal on the lines separating the jaws; the upper jaw being adapted to be bent down upon the lower jaw and to grip the paper without perforating or mutilating the same; substantially as described.

2. A metallic paper fastener having an opening in the body thereof to receive assembled sheets of paper; a tongue adapted to be bent down upon the sheets of paper inserted in the opening and without puncturing the same; a score struck up from the body of the metal on the line of bending; and upper and lower jaws; substantially as described.

3. A metallic paper fastener having an opening in the body of the metal to receive assembled sheets of paper; an upper jaw; a lower jaw; and a tongue integral with the body and adapted to be bent down upon the sheets of paper inserted in the opening and without puncturing the same, the extreme end of the tongue when turned down occupying a position adjacent and in line with a score struck up in the metal, whereby when the jaws are bent the paper will be forced by the tongue into the score and securely held, substantially as described.

4.. A metallic paper fastener having an opening in the body of the metal to receive sheets of paper; a plurality of jaws; and two scores on the lines of bending; substantially as set forth.
